WURENCH.

Application iled February 5, 1923. Serial No. 616,983.

To @ZZ Vwhom if may concern.:

Be it known that l, FnnDnnror; VVArERs, a citizen of the United States, residing at Lyons Falls, in the county of Lewis and State of New York, have invented certain new and useful improvements in Vil'renches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to wrenches and has for an objectfto provide a wrenchembodying many and improved features of rigidity of construction and convenience of operation.

A further object of the invention is to provide a wrench embodying new and improved means for reaching intoy relatively inaccessible positions.

With these and further objects in view the invention comprises certain novel units, elements, constructions, combinations and mechanical movements, as disclosed. in the drawings, together with` equivalents thereof, as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a perspective view of the wrench in one of its several adjusted positions.

Figure 2 is a longitudinal sectional View through the wrench;

Figure 3 is a longitudinal sectional view taken on line 3-3 of Figure 2;

Figure 41 is a view of the wrench with one part of the head removed, as indicated by line l-l of Figure 2.

Like characters of reference indicate cor# responding parts throughout the several views.

The improved wrench which forms the subject matter of this application comprises three major parts, a head A, a shank B and a gear housing C.

Extending longitudinally through the shank B is a shaft 10 having at one end a beveled gear 11 and at its opposite end a worm gear 12.

r1"he end carrying the beveled pinion 11 is enclosed within the housing A. The housing A comprises two sections, a section 13 journaling a beveled gear 1e and socket 15 and a cover section 16. The end of the shaft 10 carrying the worm gear 12 extends into the gear housing C which comprises a section 17 preferably formed integral with the shank B, and a covermember 18.

Journaled also within the gear housing C is a worm 19 having an angular stud 2O extending outwardly through said gear housing and in position to be engaged by the crank 21.

The socket 15 is adapted to receive and accommodate wrench members of various sizes having uniform Shanks 22 for engaging in said socket member.

The gearhousing C may be permanently and rigidly secured together in any approved manner, as by the screws 23, but the head 16 is preferably formed to rotate at times upon the shank B. As shown, its connection is by means of a threaded end 2-1 upon the shank B, which is clamped between the sections 13 and 1G of the head by means of screws 25. By this means, loosening the screws 25 will permit the rotation of the head relative to the shank B` so that the axis of rotation of the socket 15 may be varied relative to the axis of ron tation of the worm 19. This permits the employment of the wrench in a great variety of positions otherwise practically inacces sible.

1t will be readily understood that the head A, having been adjusted tothe required o-r desired angle relative to the other parts and secured there by the clamping screws 25, the wrench will be operated by inserting a wrench of the required or desired size in the opening of the socket member 15, applying the crank 21 to the stud 2O and a rotation. of the crank in either direction will result in the consequent rotation of the socket member 15 and the wrench member carried thereby.

What I claim is 1. A wrench comprising a hollow shank, a head carried at one end ofthe shank, a gear housing carried at the opposite end of the shank, a shaft extending through the shank, a beveled pinion within the head, a beveled gear mounted in the head and meshing with the beveled pinion, a wrench socket carried by the beveled gear, a worm gear carried by the shaft within the gear housing, a worm engaging said worin gear7 an arm adapted to rotate said worm, and means to clamp the head in adjusted rotary position relative to the shank.

2. A Wrench comprising a hollow threaded shank, a head carried at one end of the shank composed of separable sections, each Carrying' part of a threaded socket engaging threads of the shank, a gear housing carried at the opposite end of the shank, a shaft extending through the shank, a Wrench socket carried rotatatively by the head7 gearing connecting the shaft with the Wrench socket, a Worin gear carried by the shaft Within the gear housing, a` Worm enraging said Worin gear, a manual arm adapted to rotate with said Worin, and means to elainp the sections of the head upon the threaded portion of the shank to maintain the head .in adjusted rotative position relative to the shank.

In testimony whereof I hereunto alix my signature.
